Honestly, I
have never thought sky would be related with the color of green!

What it's all about...

Basil
visited Dorian because he was worried about his friend's grieve on Sibyl's
death. However he was startled by Dorian's ignorance by going to Opera with
Lord Henry only one day after the tragedy, which Basil took as a negative
change in his character. Meanwhile, Basil intended to exhibit his painting of
Dorian Gray's picture in Paris, which frightened Dorian.

When Basil
would like to see his own painting, Dorian—of course—rejected. This lead to
Basil's confession on his feeling towards Dorian that was reflected in the
painting, which was the reason he rejected to exhibit it. After the painting
went to Dorian's residence, however, Basil decided to exhibit it anyway. Dorian
strongly rejected the idea and Basil kindly accepted his decision. That
conversation then encouraged Dorian to hide the painting for good in an old
room where he used to be in his childhood and youth days. At the end of chapter
X, Lord Henry lent a ‘mind poisoning’ novel to Dorian.

My random thoughts...

Hiding the
dark side

Just as
sinners like to hide their sins in the darkest ‘room’ of their souls, Dorian securely
hide the continuously-corrupted-painting into a dark old-dusty room where he
kept the key and ensured that not a single soul should ever see it.

Let the
painting bear his sin

It’s
interesting to observe how at first Dorian looked at the cruel expression in
the painting still with amazement and observation. He had observed that the
source of that cruel expression was his cruel treatment to Sibyl Vane. He knew
and admitted that he had done something bad. He wished to apologize to Sibyl
and marry her to repentant his wrongs, for who knows, his expression in the
painting might return to its original state then? But Lord Henry didn’t let him
swim in his regret, and soon influenced him to just forget it, that it was not
his fault anyway. And now, after Lord Henry ‘lifted’ his moral obligation,
Dorian felt burden with his conscience (the corrupting-painting), and finally
decided to hide it forever and let it rotten, letting him freely committing
more and more sins. Now that the conscience had been muted, nothing would
prevent him from falling deeper down…
